Abstract :
This work lays out our investigation into the non-invasive, automatic measurement of blood pressure. We have investigated the use of a thermal camera to detect changes in surface temperature due to the pulse in the radial and ulner arteries and then moved on to detecting the same pulse using a low-cost thermistor. Our preliminary results presented here indicate that the pulse is indeed detectable using a simple thermistor apparatus and that it is possible to develop a calibrated system to measure blood pressure using the pulse transit time method.
